WebWhat is the Bohr Effect? The Bohr effect explains red blood cells’ ability to adjust to changes in their biochemical climate, maximizing haemoglobin-oxygen binding potential in the lungs while enhancing oxygen delivery to the most demanding tissues. The Bohr effect was first described in 1904 by Christian Bohr, a Danish physiologist.
